Olaplex Number 3 Hair Perfector 100ml is a deep treatment that reconnects bonds in the hair that have been broken by colouring, lightening or excessive heat styling.

You can do this treatment once a week at home regardless of whether or not you colour your hair. If you re wondering if this treatment is for your hair, you ll be happy to know Olaplex is compatible with all hair types, from virgin, to coloured, textured, or highly compromised. If your hair falls into the highly compromised category, we recommend using the No. 3 as a treatment 2-3 times a week in combination with your favourite moisture and protein treatments where applicable. Directions: Apply a generous amount to towel-dried hair and comb through. Leave on for a minimum of 10 minutes. Keep in mind, the longer it s on, the more effective it is, especially for hair that is compromised. We ve seen great results from people who leave it on 30 to 90 minutes! Rinse, shampoo and condition. Remember, this is NOT a conditioning treatment OR a leave-in treatment. It is meant to be shampooed out of the hair and followed up with your regular shampoo/condition regimen. Voila! Style as you normally would.
